WILLIAM ARTHUR RAYMOND, OF SOUTH BEND, WASHINGTON.

HOLDER FOR INCANDESCENT LIGHTS.

To all whom it may concern:

Be it known that I VVILLIAM ARTHUR RAY- MOND, a citizen of the United States, and a resident of South Bend, in the county of Pacific and State of WVashington, have invented certain new and useful Improvements in Holders for Incandescent Lights, of which the following is a specification.

My invention is an improvement in holders for incandescent lights adapted to be used in a locomotive headlight, for instance, in place of a carbon ejector, so that the light will be supported at the focus of the reflector.

In the drawings:

Figure 1 is a side view of the improved support Fig. 2 is a vertical section of the clamp for embracing the light;

Fig. 3 is a top plan View of the upper split ring;

Fig. 4 is a similar view of the lower split ring, with the standard in section.

As a rule, when locomotives are equipped with incandescent headlights, the entire headlight, reflector and brackets, are especially designed for the incandescent lights, and hence the change from are lights is expensive. The object of the present device is to provide a means capable of attachment to any headlight, for supporting an incandescent bulb at the proper point in the reflector.

With this object in view I provide a staff or standard 1 which has its upper portion 2 given a quarter turn, as shown, to bring its wide dimension perpendicular to the wide dimension of the body of the standard, and this portion 2 has split rings 3 and 4 for embracing the socket 5 of the bulb, indicated at 6.

The ring 3 is a plain split ring, being riveted to the portion 2 of. the standard, at a point diametrically opposite the split of the ring, and it will be noticed from an inspection of Figs. 3 and 4 that the portion 2 of the standard is curved to lit the rings' The ring 4 is also a split ring and it is also riveted to the standard in spaced relation to the ring 4.

Referring to Fig. 2 it will be seen that the center part of the portion 2 or" the standard is offset away from the globe, and that the ring 4 is secured to that face of the portion 2 which is remote from the bulb, while the ring Specification of Letters Patent.

Application filed July 2, 1920. Serial No. 393,633.

3 is secured to that face which is adjacent to the bulb.

The ring 4 is provided at one side of the split with a slot 7 and at the other side the ring has a tongue 8 which is adapted to engage the slot, to connect the two ends. This tongue, as shown more particularly in F ig. 2, is passed from within outward and the ring may thus be gripped upon the socket 5. The ring 3 embraces the bulb at the reduced portion adjacent to the socket, and the socket is thus firmly held in place.

In the Pyle llational electric headlight. the lower electrode is held in a socket (not shown) which is connected to a lateral arm 9 extending from the lamp column 10, which in turn extends upwardly from the lamp base 11. The upper end of the column 10 has means for supporting the upper electrode (not shown). When the improved holder for the incandescent bulb is to be applied, I remove the electrodes and their supports and insert the lower end of the standard 1 in the clamp indicated generally at 10 which connects the lower electrode socket to the lateral arm 9. The wires 12 of the lamp are connected with the binding posts 13 and 14 on the lamp column. Thus any are headlamp may be converted into an incandescent headlight merely by removing the electrodes and connecting the element 1-2 to the lamp column.

No change is required in the construction oi the headlight, and it is not necessary to interfere Wlitll the reflector nor with its mounting.

I claim:

An attachment of the character specified, comprising a bracket consisting of a plate twisted intermediate its ends to cause the wide dimension of its ends to extend at approximately right angles, one of said ends being adapted for engagement by the holding clamp of a lamp column, the other end carrying a pair of split rings spaced apart longitudinally of the said end and adapted to engage about the socket of an incandescent bulb, one of the ends of the lower ring havmg a tongue and the other a slot for engagement by the tongue to clamp the ring on the socket.

WILLIAM ARTHUR RAYMOND.
